International longevity comparisons.

Japan leads the world in life expectancy with an average future lifetime of 78.9 years. Iceland is next, followed by Sweden and Switzerland. The United States ranks 11th at 75.4 years. In the past decade, United States' men generally narrowed the expectation of life gap among other industrialized nations, but for the country's women the experience was uneven. These international longevity disparities for men and women in the United States narrowed considerably at later years of age. For instance, the United States-Japan expectancy gap is currently 2.0 years at age 45 and declines to about 0.9 years at age 65.
